Known as the cross-race effect (CRE), psychological research has consistently shown that people are extremely inept at identifying the face of a person who is from a race that is different than their own.

race of faces, generally, their own race, than with other races. By contrast, most
people have roughly equal amounts of contact and experience with males and

This phenomenon, termed the Other-race effect, has been examined extensively
in experimental studies, and archival analysis of DNA exoneration cases shows
that it is also a significant problem in actual cases. In their analysis of 77 ...

Among college students whose mothers lacked a college degree, six-year graduation rates were higher for women than for men, but there was no such gender gap among black students whose mothers had a degree.
That’s one finding of a study published in the American Journal of Orthopsychiatry (log-in required).

Even in multicultural nations interracial relationships and marriages are quite rare, one reflection of assortative mating. A relatively unexplored factor that could explain part of this effect is that people may find members of their own racial group more attractive than members of other groups. We tested whether there is an own-race preference in attractiveness judgments, and also examined the effect of familiarity by comparing the attractiveness ratings given by participants of different ancestral and geographic origins to faces of European, East Asian and African origin. We did not find a strong own-race bias in attractiveness judgments, but neither were the data consistent with familiarity, suggesting an important role for other factors determining the patterns of assortative mating observed.

The Other-race effect is the reduced ability to recognize strangers' faces of another race relative to strangers' faces of one's own race. Many studies have demonstrated the reliability of this effect (see Meissner & Brigham, 2001, for a review). And a number of studies suggest that experience beginning in infancy is important for the development…

We've all had an Asian person say, 'All you Americans look alike' - but they aren't being racist, there may be some biology at work.The brain works differently when memorizing the face of a person from one's own race, according to a study which used EEG
